Performance and recovery: stress profiles in professional ballroom dancers

Like other athletes, ballroom dancers often compete in short time in different countries under condition of high stress, subjecting them to risk of injury and burnout. In the present study, we measured the aerobic and anaerobic capacities (both during dance and during a simulated ballroom competition), agility, hand and abdominal strength, jumping capacity, flexibility, and balance in 16 top-level couples of ballroom dancers (8 males, 8 females). The in-season level of perceived stress and recovery was assessed using the Rest Q 76 questionnaire, and the relationship with aerobic and anaerobic capacity and with the other tests was studied. Our results show a very high level of aerobic/anaerobic fitness in this population, as well as a high level of stress in males. Balance and experience (age of the subjects) appear to be key characteristics linked to the position in the IDSF World Ranking (world ranking points = 8.67 x age + 5.86 x balance + 1174.65; R2 = 0.740). Emotional stress (r = 0.83, p = 0.04), social stress (r = 0.72, p = 0.032), and sleep quality (r = 0.92, p = 0.001) scales of the Rest Q appear also to be linked with balance but only in females.
